wait for the drop 

a term used in a group of people listening to house, techno, dubstep or DnB. a drop is usually preceded by an electronic drum beat and a modulation occasionally prompting one of the listeners to yell "here comes the drop!" the drop itself is a heavier beat, containing synth sounds and a heavier bass, anticipating listeners to attempt at dancing. of course none of them can because they're all a bunch white high school/college kids stooned and/or drunk off their ass.

douchey fratboy that discovered dubstep 3 hours ago: hey man this music sucks!

intellectual electronic music fan: nah brah just wait for the drop!
